"Couple that with the fact that only 1.5 volts are required to run the modules at the aggressive rated timings and speeds of 1600Mhz 7-8-7-24. The other bonus shows up in a system that is slightly better in the power efficiency department just because you are not burning that energy to get your results. Even if you have to bump the volts up a notch or two when overclocking, the heat spreaders are large enough to handle the thermal load."
